To all 'whom t may concern: i

Be it known that I, HoRAoET. SPENCER, a citizen yof the United States,residing at Knoxville, in the county of Knox and State of Tennessee,have invented a new and useful Insect-Powder Blow-er of the BellowsType, of which the followingis a speciti cation. y y

This invention has reference to insect powder blowers, the primaryobject of the invention being to provide novel means for discharging thepowdered materialy from the body portion `of the `blower or bellows, sothat the material will take a `swirling motion tov insure the same beingproperly distributed.

Another object of the invention is to provide means for securingvthedischarge tube within the body 4portion of the blower, whereby the tubewill be held in spaced relation with the wallsof the blower.

A. still further object of the inventioii is t0 provide novel andinexpensive means for securing the flexible walls of the blower to thebody portion of the blower. y

With the foregoing andother objects in View which will appear as-thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed, and claimed, it being understood that .changes in the preciseembodiment of the the bending of the same into shape;

- `Re erring to the drawings in detail, the

body portion of thebellows is formed preferably of ply wood material,but it is to be understood that the material of which the body portionismade, may be of any light substance, to render the device easilyoperated.

TheJ body portion which is indicated at 5, embodies opposed sections 6and 7, which sections are connected at "their ends by means of a stripof leather, or other flexible element, as indicated at 8, the strip ofleather being secured to the sections 6 and 7 as by the securing meansindicated at 9.

The discharge tube which forms an imi portant feature ofthe invention is`formed of a sheet of comparatively thin metal, the same being passed`through a suitable machine to form tongues 11 that are arranged in theblank diagonally, as shown by Figure These tongues 11 are stamped fromthe `body portion of the blank and are bent inwardly providing openings12 to admit material to pass into the discharge tube, which is indicatedat 13.

Adjacent to one end of the blank, are spaced tongues 14, which are alsostamped from the blank, to provide openings 15, the

`tongues 14 Ibeing brought together in a manner as shown' by Figure 2 ofthe draw ings to direct air and material to the interior of the tube.`

Formed in the blank adjacent to one end thereof, are the transverselyextending ribs 16 disposed in spaced relation with each other andconstructed so that they will form circular enlargements onthe tube whenthe blank is formed into a tube.

The washer wh'ichis shown more particularly byFigures `5 and 6 of thedrawings, is

sections adjacent to the forward ends thereof, which opening is designedto accommodate a portion of the discharge tube as i tube.

clearly shown `by Figure 1 yotthedrawi'ngs Metallic washers indicated at10 Contact with the `overlapping- '.ends of ythe lflearible member .10.,the `washers :also ,contacting with the ribs 16 to clamp thetlexiblematerial, securing vthe endsy together, and at the same timeproviding a support for the discharge As shown by Figures 7 and ,8 fof:thezdranh ings, the flexible `element 8 is secured'to .the sections `6and 7 by means ot ythe Wires 18, which wires are stretched over thesection to force portions of theflexible [element 8 into` the grooves 19formed in ,the section. lVhile I have shown the `fiexible member 8 assecured to the section 6, it is to be understood that :a similar,connection is :madebetween the flexible .element 8 .and section 7..

Ihen the wires 18 have been properly posi:

tioned, they are @soldered by means ot' the soldering materialindicatedat .20. y lIn the form of the [invention as illustrated by.Figures -9 and .10 of the drawings,

the section 6 ,-isormed with "fa .depressed portion 21which is of iawidth equal tothe width .of the band l22 employed for securing the'flexible element 8 to ,the section. v The band is positioned over `theflexible member .8 .at a point ,where the same will forcepordrawings,has its ends'overlapped as -at 27,

where the overlapped ends are secured by means of the 'rivets 28, solder`being applied as at 29 for further securing .theends together.

lis shown by Figure 1Q ofthe drawings,

a pairof wires 30 areemployed, which wires `have their ends twistedtogether as at `31, where Athe same may be twistedtegether in anysuitable manner. Handles 17 are secured-.to the` body portion of theblower as shown by Figure k1 of the drawings, the

`have provided `an. inexpensive but efficient means for securing theilexible element to the body. portion of the device.V

In the use of the device, it is obvious that as the handles .-17 are,moved towards each other, the side portions or sections 6 and 7 :of theblower, will also be moved towards each other, which movement forcesmaterial through the-openings 12 and'15,-thetongues 11 and 14 directingthe material in a circular path-throughout thelength of the dischargetube 13.

It might be further stated that `due to the lconstruction of thedischarge tube, lumps which may be present will .be broken anddischarged inga powdered form.

Having thus described the invention, what is claimed as new is v 1. Aninsect powder blower comprising a body portion, a discharge tubecentrally located within `the body .portion` said discharge tube havingopeningsy ,tormedfin the side walls thereof, tongues disposed adjacentto the openings, .saidtongues adapted` to direct material spirallythrough Vthe discharge tube, and means for voperating the bellows.

2. An insect powder blower comprising a within the, body portion, saidtube having vopenings formed in `spacedrelation with eac-h `other .anddisposed spirallyot1 the tube, means adjacent to the opening fordirecting material in a spiral path through the tube,

vand meansfor operating the bellows.

3. An insect powder blower ,comprising a body portion, a washer disposedat one end of "the bellows, a discharge tube having spaced ribs, saidwasher adapted` to grip the tube between the ribs, said tube havingopenings ormed in spiral relation, .and means adjacent to the openingsfor directing mate rial to the interior-of the tube.

In testimony -that I. claim the foregoing as my own, I have heretoaiiixed mysignature inthe presence of two witnesses.
